Net::HTTPBadResponse（错误的标题行格式）

Question

请帮助我理解，我做错了什么？ 我需要从我的 Rails 应用程序向 api 发出 POST 请求，我首先尝试使用 gem“法拉第”，然后使用“net/http”。来自服务器的响应相同。帐户创建，但出现错误：

Net::HTTPBadResponse（错误的标题行格式）

class Connect
 require 'uri'
 require 'net/http'
 require 'net/https'
 require 'faraday'

 def initialize(email, password, account)
   @base_url = "https://example.com"
   @client_id = ENV["client_id"]
   @client_secret = ENV["client_secret"]
   @email = email
   @password = password
   @account = account
 end

 # method with net/http
 def create_account

   @toSend = {
     first_name: @account[:first_name],
     last_name: @account[:last_name],
     client_id: @client_id,
     client_secret: @client_secret,
     email: @email,
     password: @password
   }.to_json

  uri = URI.parse("#{@base_url}/endclient/api/account")
  https = Net::HTTP.new(uri.host,uri.port)
  https.use_ssl = true
  req = Net::HTTP::Post.new(
    uri.path,
    initheader = {
                   'Content-Type' =>'application/json',
                   'Accept' =>'application/json'
    }
  )
  req.body = "#{@toSend}"
  res = https.request(req)
 end

 # faraday method
 def make_account

  conn = Faraday.new(:url => "#{@base_url}") do |faraday|
    faraday.response :logger                  
    faraday.adapter  Faraday.default_adapter
  end

  params = { first_name: @account[:first_name],
    last_name: @account[:last_name],
    client_id: @client_id,
    client_secret: @client_secret,
    email: @email,
    password: @password
   }.to_json

  response = conn.post do |req|
    req.url '/endclient/api/account'
    req.headers['Content-Type'] = 'application/json'
    req.headers['Accept'] = 'application/json'
    req.body = params
  end
 end
end

通过Postman成功完成此请求，因此api的端点正在工作。

请帮助我了解标题有什么问题？ 提前致谢！

更新：

这可能有问题吗？

Cannot render console with content type application/jsonAllowed content  types: [#<Mime::Type:0x00000003661658 @synonyms=["application/xhtml+xml"], @symbol=:html, @string="text/html">, #<Mime::Type:0x00000003660fc8 @synonyms=[], @symbol=:text, @string="text/plain">, #<Mime::Type:0x0000000365ca68 @synonyms=[], @symbol=:url_encoded_form, @string="application/x-www-form-urlencoded">]

如果您想要一个可以轻松混合到类/模块中的 http 库，我会推荐 httparty 而不是 Faraday 或只是简单的旧 Net::HTTP。

require 'httparty' # Requires go at the top of the file. Not in class body.

class MyApiClient
  include HTTParty
  base_uri 'test.example.com'
  # Tells Httparty to send JSON for all requests.
  format :json 

  # @see https://robots.thoughtbot.com/ruby-2-keyword-arguments
  def initialize(client_id: ENV["client_id"], client_secret: ENV["client_secret"])
    @options = { 
      body: { 
        client_id: client_id, 
        client_secret: client_secret
      } 
    }
  end

  # @return [HTTParty::Response]
  def create_account(first_name:, last_name:, email:, password:)
    # ActiveSupport method that creates a copy so that we don't 
    # alter the instance options as a side effect.
    opts = @options.deep_dup 
    opts[:body].merge!(
      email: email, 
      password: password,
      first_name: first_name,
      last_name: last_name
    )
    self.class.post('/endclient/api/account', opts)
  end
end

好消息是httparty 将完成所有工作，解析与 JSON 之间的参数并发送正确的标头。它还负责构建 URI 的枯燥工作。

注意方法签名略有不同：

client = MyApiClient.new
response = client.create_account(
  first_name: 'John',
  last_name: 'Doe',
  email: 'john.doe@example.com',
  password: 'abcd1234'
)

Answer 2

API 端出现问题，标头符号错误。
